Nonlinear behaviors of single-phase full-bridge inverters via varying load resistance

The main circuit is a voltage-controlled single-phase inverter in this paper. The work investigates on nonlinear behaviors of fast-scale instability phenomena with this inverter. First, the operating principle of a single-phase full-bridge inverter is examined. Hence, relational mapping state-space equations are then derived. Additionally, we present the MATLAB/SIMULINK tool for simulation and IsSpice is adopted for approximately physical simulation. The variable load resistance is selected to analyze the fast-scale instability waveforms of the inductor current and output voltage. Simulation results clearly indicate that MATLAB/SIMULINK and IsSpice can provide consistent results and validate the mathematical models of single-phase full-bridge inverter.
